So every time that i press on my trackpad button, it makes this weird clicking noise. It wasn't there before, but now it's like, every time i press it, it makes that noise until i press it slightly hard and it goes away for about 5 minutes and it starts doing it again. I tried removing the battery and looking at the trackpad and there doesn't seem to be anything really stuck, from what I can see, but my friend suggested to use a can of compressed air. So what do you guys think? Is it safe to remove the battery and use compressed air by the trackpad to remove any foreign objects which is causing this odd clicking noise? Or could it be something else? I'm still under warranty, but the closest apple store is in the next province, so I'll have to send it to really get it fixed by apple. Thanks!
